Searching for individual characters in an image

Question

Java

Somehow I didn't have to work with images and now there was a problem on the image (containing only plain text) to find individual characters and crop them individually. Of course, I can roughly imagine how this is done, but maybe there is a ready-made solution on ImageMagick, so as not to reinvent the wheel? Desirable solution for java.

I further want to make more space between characters (mostly numbers), run blur 1x1 through imagemagick and this way recognition in tesseract goes much better.

You can see the contour analysis algorithm:
